THEORY OF OPERATION
The VT7600 uses a Viconics proprietary adaptive logic algorithm to control the space
temperature. This algorithm controls the heating / air conditioning system to minimize
overshoot while still providing comfort. It provides exceptional accuracy due to its unique
PI time proportioning control algorithm, which virtually eliminates temperature offset
associated with traditional, differential-based on/off Terminal Equipment Controllers.
Fig.2 - On/Off mechanical control vs. PI electronic control.
If replacing an existing Terminal Equipment Controller, label the wires
before removal of the Terminal Equipment Controller.
Electronic controls are static sensitive devices. Discharge yourself
properly before manipulating and installing the Terminal Equipment
Controller.
A short circuit or wrong wiring may permanently damage the Terminal
Equipment Controller or the equipment.
All VT7000 series Terminal Equipment Controllers are designed for use
as operating controls only and are not safety devices. These instruments
have undergone rigorous tests and verification prior to shipping to ensure
proper and reliable operation in the field. Whenever a control failure
could lead to personal injury and/or loss of property, it becomes the
responsibility of the user / installer / electrical system designer to
incorporate safety devices (such as relays, flow switch, thermal
protections, etc…) and/or an alarm system to protect the entire system
against such catastrophic failures. Tampering with the devices or
unintended application of the devices will result in a void of warranty.

Humidification process
Humidification process will only be allowed when the Terminal Equipment Controller is in
heating mode (System Mode = Heat or System Mode = Auto and effective mode at the
Terminal Equipment Controller is heat). If there is a humidification demand and the fan is
OFF, the fan is first turned ON and the humidifier output is then activated.
Other than having the RH setpoint, the following events can stop the humidification
process at any time: RH sensor is out of range, System Mode is switched to Off or Cool
and the System Mode = Auto but the room’s effective mode changes from Heat to Cool
Dehumidification process
If (Dhu LCK) Dehumidification Lockout Functions is set to On (Enabled):
Dehumidification process will only be allowed when the Terminal Equipment Controller is
in cooling mode (System Mode = Cool or System Mode = Auto and effective mode at the
Terminal Equipment Controller is cool). If there is a dehumidification demand and the fan
is OFF, the fan is first turned ON and the dehumidification output is then activated.
Other than having reach the dehumidification setpoint, the following events can stop the
dehumidification process at any time:
RH sensor is out of range
System Mode is switched to Off, Heat or System Mode = Auto and effective
mode at the Terminal Equipment Controller is Heat
The room temp drops below the cooling setpoint minus the deadband value
The Outside air temp is below the Dhu OALK parameter
If (Dhu LCK) Dehumidification Lockout Functions is set to Off (Disabled):
Other than having reach the dehumidification setpoint, the following events can stop the
dehumidification process at any time:
RH sensor is out of range
System Mode is switched to Off
The Outside air temp is below the Dhu OALK parameter
Dehumidification process is allowed when the Terminal Equipment Controller operates in
all system modes except Off. If there is a dehumidification demand. If the fan is OFF, the
fan is first turned ON and the dehumidification output is then activated.
There is NO active temperature lockout protection in this mode. If the dehumidification
process causes the room temperature to rise or fall, the Terminal Equipment Controller
will react by either activating the cooling or heating outputs based on its current system
mode settings.

*Scheduling consecutive events to the same time will cause the Terminal Equipment
Controller to choose the last event as the time at which it will set its schedule. In the above
example for Saturday, the Terminal Equipment Controller will control to the occupied set
point from 8:00 AM until 11:59 PM. Since it is desired to be in occupied mode throughout
the night, then it is necessary to schedule the first event on Sunday at 12:00 AM. The
Terminal Equipment Controller will force a one minute unoccupied period for a one minute
period (between 11:59 PM and 12:00 AM on Saturday)
